Gold medalists of the natural world

Who’s fitter
than an Olympic athlete? In the spirit
of the 2012 Olympic games, the International Union for Conservation of Nature (IUCN), nominated
its “gold medalists of the natural world”. The Guardian newspaper in the UK publicized
this article, adding some excellent photos of the winners.

Here are the
winners of a few of the athletic events highlighted by the IUCN:

Cheetah on the move

Sprinting – The cheetah wins the sprint
competition, running at speeds of 112 km/hour (70 mph) over short distances. Sarah, a cheetah at the Cincinnati Zoo, ran
the 100-meter dash in 6.13 seconds, almost 3 seconds faster than Usain Bolt's world record
time of 9.58 seconds (also in 2009, a good year for speed!). Photo: http://www.wallpapersfreebackgrounds.com//running-cheetah.html

Arctic tern - taking a break?

Marathon– Arctic terns are the distance
champions. Each year for up to 30 years,
these birds navigate a round-trip migration of over 70,000 km between the
Arctic, where they breed, and the Antarctic oceans, the longest-distance
migration of any bird. Photo: Tom Curtis, http://www.freedigitalphotos.net

Common froghopper

High jump – The Common Froghopper, a bug common across Great
Britain, captures the gold in the high jump competition. This super bug can jump 115 times its own height
- equivalent to you or me jumping 200m!Photo: copyright-free-pictures.org.uk

Marine iguanas sunning with a sea lion

Triathlon – The Galapagos marine iguana
is the world’s only lizard that runs on land and swims (to
depths of 20m) beneath the ocean. The
ability to move well in both arenas helps the iguana live on isolated islands
that may have limited food available. They have yet to master the art of cycling,
though. Photo:

Young gibbon hanging on

Artistic gymnastics – The winning
gymnasts here were the agile gibbons. Gibbons
gracefully swing, hand-over-hand (a movement called brachiation), through the
trees, and they can reach a branch up to 15 m (50 feet) away in a single swing. Like the tumbling runs of the Olympic
gymnasts, gibbons can twist and turn while they swing. This
one may be considering a front flip? Photo: Glen Bowman, http://animalphotos.info

Wilson's bird of paradise

Rhythmic gymnastics – Males of many of
the 40 bird of paradise species dance to attract females, and their sometimes
elaborate costumes (feathers) and routines take getting the girl to a higher
level. Some dance alone, while others assemble
at a single spot in gatherings called “leks”, where they to compete for passing
females by showing off their feathers and dancing skills (team medal, perhaps?). Photo: Doug Hanson

Peregrine falcon flying

Diving – Peregrine Falcons can reach up to 200mph (320km/h) when
swooping through the sky in pursuit of prey, usually other birds. The fastest
ever dive recorded was 242mph (390km/h).
Peregrines have special nostrils and eyelids that allow them to breathe
and see during these super-fast dives. Their
main dive style involves folding back their wings and tail, tucking in their feet,
and swooping downward, striking the passing bird with a clenched foot. The impact stuns or kills the prey, and the
falcon then turns to catch it in mid-air. Photo: Kevin Cole

Oxpecker riding an impala

Equestrian
– This medal is shared by the yellow-billed oxpeckerand red-billed oxpecker,
two bird species that ride on the backs of African grazing mammals, including
cattle, eating ticks and other parasites living on their host. Even their courtship takes places on top of
their hosts.

Rhinoceros beetle

Weightlifting
– The rhinoceros beetlecan carry loads of more
than 30 times its own weight, making it one of the world’s strongest animals (though,
apparently, some dung beetles may be equally strong). In comparison, Hossein Rezazadeh’s official world record for
the heaviest individual weight lifted by a human in an Olympic competition is
263.5kg (580.9 pounds), approximately 1½ times his own bodyweight and
equivalent to lifting four average-sized people. Photo: ThinkQuest.org

Of course
fitness in the animal world varies by species – running fast is important for
cheetahs but not for gibbons, falcons, or oxpeckers -- each species relies on
its unique combination of characteristics to survive and reproduce. In fact, you can click here for a whole page of natural born record holders.
